Nicely-appointed, clean place about 5 minutes walk from BTS station Phrom Phong. Particularly enjoined the proximity to a range of good quality Thai restaurant (I tried 3 different fantastic places within 10-15 minutes walk). Also there are several massage places both high end and cheap (but no less good) nearby, a good way to end my evening after walking around Bangkok was dropping by for a massage before walking to my bed 2 minutes away :)
One con is you can hear traffic from the room, but I didn't find it a trouble to sleep.
